Penetration Quartz
This is the name given to Quartz Crystals that have another crystal that has formed inside of the main crystal, similar to manifestation quartz but the small crystal is not totally enclosed. This crystal formation is also known as “inner child crystals”.

Inner Child Crystals can assist to bridge between worlds. It may be the inner and exterior worlds between your inner and outer Selves or between yourself and others in the physical world in which you now live. They are helpful in any area you might envisage needing a bridge. They can help you heal and get in touch with your inner child, bridging the gap between your outer self and your inner self.
